Abstract
Disease patterns and manifestations may vary among different populations and change over time. The purpose of our study was to define the demographic, clinical, roentgenologic, and laboratory findings in a recent cohort of psoriatic arthritis patients followed up in rheumatology clinics in northern Israel. We conducted a cross-sectional study of 149 psoriatic arthritis patients. Demographic, clinical, laboratory, and radiological data, with emphasis on the pattern of arthritis, treatment regimens, and co-morbidities were obtained from patient interviews and rheumatology file reviews. The mean age of our patients was 58.2, with a female preponderance (57.3%). Skin involvement preceded the arthritis or was diagnosed simultaneously in 90.1% of cases. The most common joint involvement was an RA-like arthritis (49.7% of the patients) correlating positively with age, female gender, and disease duration. Dactylitis and nail involvement were observed in 33.6 and 36.2% of the patients, respectively. Radiographic bone erosions were noted in a third of the patients, correlating with DIP and RA-like arthritis patterns. Most patients were treated with methotrexate (73.8%) and a combination therapy (41.4%). An increased incidence of hypertension, hyperlipidemia, and diabetes mellitus was noted in our cohort compared to the general Israeli population. Our survey, the first of its kind conducted in Israel, noted a relative increase in the polyarticular manifestation of PsA and a decrease in spondyloarthropathy, compared to historic series, with more aggressive disease found in women above the age of sixty. These findings are in line with recent surveys.
